Cathie Wood's Ark Invest executed a significant portfolio reshuffle on Monday, August 31, 2026, divesting positions in Palantir Technologies and Advanced Micro Devices while substantially increasing its holdings in Block Inc. and Circle Internet Group. The investment firm purchased 456,059 shares of Block, the fintech company led by Jack Dorsey, for approximately $37.4 million across its ARKF, ARKK, and ARKW exchange-traded funds. This acquisition came as Block's stock closed at $82.02, down $1.85 for the session. The move follows Block's strong second-quarter financial results reported in early August, where the company posted earnings of $1.02 per share and revenue of $6.
